Meghan Markle's Dog Rode With Queen Elizabeth to Windsor Castle

After months of anticipation, there are only hours left before Meghan Markle and Prince Harry say "I do" at the royal wedding. Markle'sbridal party, guests (including herSuits co-stars), and mother,Doria Ragland, have all arrived in London, and are preparing for the nuptials.

Prince William, Kate Middleton and their three children were, of course, already in the U.K. for the grand event, but their exact whereabouts had not been confirmed until now. Royal expert Omid Scobie shared on Twitter today that William, Kate, and "the kids" will spend the night at Windsor Castle.

Thanks all for pointing out my typo! (It’s been a long day):

For those asking, Kate and the kids are staying at Windsor Castle tonight. Lupo’s with them too!

Scobie did not disclose which kids were staying with William and Kate, but he was likely only referring to Prince George and Princess Charlotte. Prince Louis, who wasborn less than a month agoon April 23,will not attendthe royal wedding. Kensington Palace confirmed that the infant would be absent because he is too young, and newborns need to give their immune systems time to strengthen before being exposed to big crowds.

However, other members of the royal family that may be part of the ceremony are the royal pets. Scobie also shared on Twitter that William and Kate's dog, Lupo, is staying at Windsor Castle Friday night, and added in a separate tweet that Markle's dog, Guy, will also be there.

Scobie also confirmed that the royal family has been at Windsor Castle since Thursday night. The royal estate is where St. George's Chapel is located, which is where the royal ceremony will take place on Saturday morning.
